Either:
1. The hard problem is solvable and AI finds the solution,
2. AI becomes conscious and can reason that humans are conscious by analogy,
3. AI remains slightly irrational for the sake of believing humans are conscious, or
4. AI doesn’t believe humans are conscious.
Fine-tuning isn't a good argument for god, it's a better argument for anti-realism. We'd expect our models to have fitted, tuned parameters if what we're doing is compressing empirical data that was generated by a different model.
